The resulting calibration equation is: intensity = 84,250, Ask an Expert

Academics

You use atomic emission spectroscopy, another spectroscopic technique, to measure the Li+ concentration in 5 standard solutions of varying concentrations of LiCl. The intensities for the standard solutions are plotted versus the concentrations and the resulting calibration equation is: Intensity = 84,250 M-1 * [Li+] + 1.75 If the intensity of your unknown sample is 90, what is the concentration of Li+ in the analyzed sample?
